imarith overwrite WCS problems

Hey all,

I'm having trouble keeping my WCS header information intact when I overwrite an extension of a fits file. I have the following situation (where # is the extension number):

> imar image1.fits[#] / image2.fits image1.fits[#,overwrite]

where image2 is a simple fits file, no extensions. The data comes out correct, however the WCS information that was in the original image1.fits extension header is not present afterwards. Any workarounds or fixes?

Thanks
